AUTOMATIC SOAP-PRESS.

SPECIFICATION forming part of Letters Patent No. 487,818, dated December 13, 1892.

Application tiled Iebruary 26, 1892. Serial No. 422,834. (No model.) i

To all whom it may concern.' Y

- Be it' known that I, OTTO W. BAND, of Brooklyn, in the county of Kings and State Of New York, have invented certain new and useful Improvements in Automatic Soap-Presses; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the figures of reference marked thereon, making a part of this specification- The object of my invention is to produce a machine in which long bars of soap are fed automatically to a cake forming and pressing mechanism in which at one operation cakes of any desired shape may be formed and separated from each other.

To this endA my invention consists in the mechanism hereinafterdescribed and claimed.

In the accompanying drawings, Figure 1 is a plan view of the machine. Fig. 2 is a side elevation of the same, partly broken out. Fig. 3 is a view, partlyin elevation and partly in transverse section,with a part of the feeding mechanism broken away. Figs. 4, 5, and 6 are detail views, on an enlarged scale, of a portion of one of the die-rolls.

Upon a suitable base 10 are erected the side frames 11 and 12, which support the cake forming and pressing devices. A shaft 13 rotates in bearings, also supported by the base, and is fitted with driving-pulleys 14 and a pinion 15. The latter meshes with a gear 16, fast upona shaft 17, which is journaled in the side framesll and 12 and has fixed thereon a gear 18. The latter drives a gear 19, of.

equal size, which is iiXed to a shaft 20, journaled in the said frames 1l and 12 above the shaft 17. The two shafts 17 and 2O bear, respectively, the lower and upper die-rolls 2l and 22. The shaft 17 may also bear a bevelgear 23, which meshes with a bevel-pinion 24 upon the lower end of a vertical shaft 25, which rotates in bearings supported by the side frame 11. Said shaft 25 has fixed thereto, near its upper and lower ends, cani-disks 26 and 27, for a purpose to be referred to.

Each die-roll is formed, preferably, with a web 28 and a lateral iange 29,(see Figs. 4 and 5,) the dies 30 being secured to the rolls by bolts, (not shown,) which pass through the iiange 29. The dies 30 are separated from each other by a space sufficient to permit the `l free movement of` a knife 31, whichis fixed to a head 32, adapted to slide in an aperture formed in the liange. A block 33 is secured on the inside of the iiange over the aperture 4.

piece 35 to keep the knife v31v normally re# tracted. Thestem 34 or the cam-piece 35v also has fixed thereto an arm 37, which bears a lug 38, projecting inwardly over the cam 35. As the rolls are rotated and as each knife approaches the point where the periperies of the two rolls are nearestits cam-lug 35 is engaged bya cam on one of the disks 26 27 and is caused thereby to thrust the knife outwardly, the gearing fordriving the rolls and for driving the cam-disks being timed, so that the cams on the disk shall (zo-operate properly with the cam-lugs on theknifestems. As the rolls continue to move each knife may be withdrawn by the spring 36, or it may be withdrawn by an incline 39, which is fixed to the inner side of the side frame 1l to co-operate with the lug 3 8.

The bars of soap might be fed to the pressing mechanism by hand; but I prefer to proy vide means for feeding the bars one at a time and in close succession from a pile of bars. To this end a frame may be supported lat one end by the side frames 11 12 and at the other by a lug 41, Near the inner end of the frame 40 is journaled a shaft 42, which has fixed thereto a drum 43, and near the outer end of the frame is journaled a drum 44. A belt 45, carried by the two drums, is provided with lugs or ears 46, which are spaced far enough apart to receive between them lengthwise a single bar of soap. A numberof bars may be placed upon the belt between guideplates 47, as represented in Fig. 2, andas the belt is caused to travel each lug or ear 46 as it comes up behind the pile of bars will engage the lowermost barof the pile and feed it forward between the die-rolls. The belt may be driven by pulleys 48 and 49, fixed, respectively, on the shafts 17 and 42 and connected by a belt 50.

In the operation of' my machine the bars IOO are fed forward singly, as just described, and as they pass between the die-rolls are pressed and formed into cakes according to the shape of the dies on the rolls. At the proximate points in the peripheries of the rolls and on the line between two successive dies the two corresponding knives are advanced, as described, each knife moving half-Way through the bar, and thereby separating each cake from its successor.

I do not intend to limit myself to the exact form of'apparatus shown in the drawings, as

the periphery of said rollA and .slightly separated from each other, a series of knives supported by said roll and adapted to move radially thereon between said dies, an independently-rotatable cam-disk adapted to actuate said knives, and means for driving said camdisk, substantially as shown and described.

3. In a soap-press, the combination of a pair of pressing-rolls, a series of dies secured about the periphery of each roll, the dies of each series being slightly separated from each other, a series of knives supported by each roll and adapted to move radially thereon be- -'tween the dies,independently-rotatable camdisks mounted upon an axis at right angles to the axis of the rolls and adapted to actuate the lcorresponding knives of each series in unison, and means for driving said camdisks, substantially as shown and described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
